In this paper, the results of an experimental investigation of the dependence of the viscosity of an LBS-4 bakelite lacquer on the conditions of ultrasound treatment (UST) are given. It is shown that the predominant factor of the decrease in the viscosity of the LBS-4 bakelite lacquer is the temperature of heating. It is determined that heating by means of UST should be preferred due to ease of exposure on the binder during the flow process. It is shown that the hangover time during impregnation should be reduced, because this results in gel formation and growth of viscosity and that the generation of gel formation using UST may reduce the time of drying of the workpiece between impregnation procedures.
